Sub-mm wavelength 3-D antennas are emerging as critical elements for ultrafast data transfer for various applications. The inherent 2-D nature of lithographic processes severely limits the available manufacturing routes to fabricate such antennas. In this work, we demonstrate a novel additive manufacturing method to fabricate 3-D metal-dielectric antenna structures at sub-mm length scale. A UV curable dielectric is dispensed from an Aerosol Jet system and instantaneously cured to form complex 3-D shapes. A metal nano particle ink is then dispensed over the 3-D dielectric, also by the Aerosol Jet technique, followed by thermal sintering. This novel method opens up the possibility of fabricating an entirely new class of 3-D antenna structures at sub-mm length scales.
